Selectivity and efficiency of pre-emergent herbicides on cassava crop
Pesquisa Agropecuária Tropical, 2013 The chemical control of weeds stands out as an important tool for obtaining high yields in cassava crops. This study aimed at evaluating the selectivity and efficiency of pre-emergent herbicides on cassava (‘Cascuda’ cultivar) crop. The experimental design was randomized blocks, with ten treatments and four replications.

Plant Breeding, EarlyView.ABSTRACT Triticale (x Triticosecale Wittmack) is an interspecific hybrid of wheat and rye. It is a promising grain and forage crop that thrives in poorer soils and low‐input farming systems. It can serve as a viable alternative to traditional small grains such as wheat and barley, bringing diversity to crop rotations and enhancing biodiversity in ...
